MACHINE FOR MAKING WATCH-PENDANTS.

SPECIFICATION forming part of Letters Patent No. 290,859, dated December 25, 1883.

Application filed March 1, 1883.

(No model.)

To all whom it may concern:

Be it known that I, OYPRIEN CHABOT, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Machines for the Manufacture of \Vatch-Pendants, of which the following is a specification.

My invention consists of mechanism, fully described hereinafter, for rapidly and economically reducing from a crude to a finished condition that part of a watch which is secured to the rim of the case, and to which is connected the ring for receiving the end of awatch-chain, this part of a watch being termed the pendant.

In the accompanying drawings, Figure 1 is a section of a watch-pendant in its crude con dition; Fig. 2, the pendant as it appears after being subjected to the action of the machine; Fig. 3, a plan view of the machine; Fig. 4, an elevation of the same; Fig. 5, a vertical section; Fig. 6, a sectional view drawn to the same scale as Figs. 1 and 2, and representing parts of the machine; and Figs. 7 and 8, detached views of part of the machine. Figs. 3, 4, 5, 7, and 8 are drawn to a reduced scale.

To a suitable table or bench, A issecured a plate, B, provided with an annular flange, a, the continuity of which is interrupted at one point, for a purpose explained hereinafter; and in this plate B and in a projection, b, on the sainea vertical shaft, D, has its bearing, this shaft being geared by bevel-wheels dto ahorizontal shaft, E, adapted to suitable bearings, e e, and provided with fast and loose pulleys for a driving-belt; or, if the machine has to be driven by hand, the said shaft may be furnished with a suitable handle. To the shaft D is secured a metal disk, G, which, in order to insure steadiness, is preferably recessed on the under side to receive a circular projection, f, which is beveled at the edges, and which forms a part of the plate B. In an annular space between the disk G and flange a of the plate B is a severed ring, H, made of tempered steel, and possessing slight elasticity. The continuity of this ring is interrupted at the same place where the interruption of the continuity of the flange takes place, a recess being formed by these interruptions, and this recess being separated into two passages, in and n, by a thin partition, 1), secured to a plate, J, the passage at being for the introduction of the crude pendants to the machine, and the other passage, 12, for the escape of the finished pendants. The severed ring H is retained within the annular space referred to and prevented from turning by bolts q, so situated that the greater portion of the ring is circumferentially free, the ends of the bolts projecting into threaded recesses in the ring. A series of radial set-screws, it, pass through the flange a of the plate A, and bear with their ends against the severed ring, but do not enter the same. The edge of the disk G is grooved to conform with the shape of the desired pendant, as shown in Fig. 6, and the inner side of the severed ringH is correspondingly grooved. The severed ring is always situated eccentrically in respect to the edge of the disk, so that the space between the two shall gradually diminish in size from the entrancepassage m to the outlet-passage n. The crude pendant is placed on the plate J at the passage m, and, being directed to the space between the disk G and ring H at the point where the said SPZLCQCOIIIIDUDlCEItGS with the passage, the pendant, as the disk revolves in the direction of the arrow, is carried through the gradually-contracted annular space and subjected to a rolling action until it reaches the outlet-passage a in a finished condition and of a shape conforming with the grooves.

Different-sized pendants are required for dif ferent-sized watches; hence the importance of providing means for adjusting the severed ring so that it can be brought nearer to or can expand, so as to be farther from the disk, as the size of the pendant may suggest.

The plate J has a projecting segmental arm, w, Fig. 7, which projects for some distance into the space between the disk G and ring H, as shown in Figs. 1 and 8, so as to afford a support for the crude pendant when the latter is first introduced into the space and before the ribs of the disk and ring have indented it sufficiently to afford a support. Some pendants are shorter than others; hence I make the plate J adjustable in order that the pendant may always be supported in such a position that the grooved portions of the disk and ring will properly coincide with and act upon the thickened portion of the pendant as the latter is introduced into the space between the disk and ring. In the present instance the plate J has a stem adapted to an opening in the plate B, and secured therein by aset-screw; but other means may be adopted for securing the plate so as to permit the adjustment of the same.

I claim as my invention- 1. The combination of the plate 13, having a flange, a, the grooved disk G, the grooved and severed elastic ring H, the bolts q, confining said ring at and near one end, and the setscrews 2, adapted to act upon the unconfined portion of the ring, as set forth.

2. The combination of the plate B, having a flange, a,with an opening therein, as described, the grooved disk G, the grooved and severed ring H, and the partition-platep, as set forth.

3. The combination of the plate 13, .the

grooved disk G, the grooved and severed ring H, means for securing the latter in place, and the plate J, having a supporting-arm, 'w, adapted to the space between the ring and disk, as set forth.

4. The combination of the plate 13, the grooved disk G, the grooved and severed ring H, means for securing the latter in place, and the plate J, having a supporting-arm, w, and adjustable vertically in respect to the disk and ring, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two snb scribing witnesses.
